Application iled June 5, 1911, Serial No. 631,422. Renewed February 6, 1915. Serial No. 6,636.

To all LU/wm t may concern Be it lrnown that I, Amann D. ANTOINE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useul Improvements in Machines for Making liiighteMantles, of which the'following is a specification.

This invention relates to machines for manufacturing incandescent mantles and more particularly to that type of machines in which the mantles are intermittentlyr advanced therethrough and during which advancement they are subjected successively to a preliminary burning ott, shaping, hardening, and immersion in a preserving solution, and one of the objects of the invention is the provision of'an improved machine of this class having means whereby a plurality oi mantles may be simultaneously treated by the various steps of Operation, thereby producing an eiiective and eiiicient machine of large capacity and ci" compact arrangement.

With this and other objects in view the invention consists substantially in the features ot novelty in the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompanying drawings, in which- Figures 1 and 2 are side elevations of an improved machine of this class constructed in accordance with the principles ot this invention.

Referring more particularly to the drawings and in the present enemplication of the invention the mechanism is supported by a frame work of any desired construction and configuration but preferably consists of a series or' spaced standards designated generally by the reference numerals 30, 31 and 32, andthese standards may be connected by members 33 (see Figs. 1 to 4c) arranged adjacent the top of the standards and extending longitudinally ot the machine (see also Fig. 10). @ne olf these members 33 is preferably arranged on each side of the machine with one extremity V34 projecting beyond the front standards and the other extremity 35 projecting beyond the rear standard 32 and if desired a brace 36 may be provided for supporting the projection por tion 34.

Arranged at intervals throughout the length of the machine are bearings 38, 39 and e0, in which are respectively journaled the shafts ot' sprocket wheels el, 42 and 13, and secured respectively for rotation with the sprocket wheels 41, 42 and 13, are sprocket wheels 421, 45 and 46. One set oit' these bearings and sprocket wheels is located on each side of the machine and the machine may be of any desired width so as to accommodate any number of mantles which are held by a support extending transversely of the machine, as will be hereinafter described. The conveyor for the mantles consists in a plurality oi sections of endless flexible members 47, 48, 19, 50, 51, which are arranged end to end so as to successively receive the mantle supports and convey them through the machine. The section l? is arranged at the front of the machine and passes over the sprocket wheel 441 adjacent the bearing 38 and another sprocket wheel 52 arranged in suitable bearings adjacent the forward end 37 of the members 33. rllie upper run of this section of the conveyor passes over a support and guide 53 which latter is in turn supported preferably from the extension 3a of the members 33 by means of uprights or standards 54 and an idler 55 may be provided and journaled in a portion of the bearing 38, over which idler the upper run of the conveyer section 57 passes so as to direct the mantle support from the conveyer section 47 to the conveyer section 48, Which latter passes over the sprockets 41, 42. The upper run of the conveyer section 48 is supported and guided by means of a guide 56 similar to the guide 53 and is held in .position by means of uprights 57. The conveyer section 49 passes over the sprockets 45, 43, with its upper run supported by a guide 57 heldin position by theuprights 58 and an idler 592l may be provided adjacent lthe end of the conveyer section 48, and oveil Which the upper yrun of the conveyer section 49 passes. The conveyer section 50 passes over the sprocket46 and a sprocket 59 which latter is journaled in a suitable bearing'preferably in the upright or standard 32 at the rear, of the machine and the upper run of this conveyer section 50 passes over a guide or support 60 held in position by means of the uprights 61. An idler 62 is also provided and lis journaled in the bearing 40 adjacent the end of the conveyer section 49 and over Which the upper run of the conveyer section 50 passes. A sprocket 63 over which the conveyer section 51 passes is secured for rotation With the sprocket 59 and a sprocket 64 is also provided for the conveyer section 51 and this sprocket 64 is jour` naled in a suitable bearing adjacent the extremity of the projecting end 35 of the member 33. An idler 65 is also provided for the conveyer section 51 and is located in close proximity to the sprocket Wheels 59, `63. Thus it Will be manifest that a mantle support which is 4placed upon the conveyer section47 Will be passed successively to the `conveyer sections, through the machine until it reaches zthe conveyer sections 51 at the other end offthe machine, and as these con'- :veyer sections are all operatively connected, ltheyivill beoperated simultaneously if moltion is imparted to one of the conveyer sec- `tions. In order therefore to impart this motion -to 'the `conveyer sections, suitable mechanism isprovided, such as a ratchet mechanism whereby intermittent movement Will be imparted to the conveyers. This 'ratchet mechanism is preferably located adjacent the exit end of the machine, although it may be located at any other point and comprises aratchet disk 66 (see particularly Fig.17) having a series of notches 67 a in its vperiphery andlthis disk 66 is secured for rotation With the sprockets 59, 63. An oscillating arm 67 is supported for pivotal movement, preferably by one extremity, and a ratchet dog 68 is pivotally mounted upon Vthe arm. The free extremity of the dog is adapted to travel about the periphery of -the'rdisk 66 so `vas-'to enter 1the shouldered notches 67a thereof, and an elastic member 69 tends normally to move the dog m a direction to enter the notches. An oscillatory provided on each side of the machine, so

that the conveyer' sections on both sides of the machine will be simultaneously and uniformly operated. One of the crank arms 71 is provided on each side of the machine and the bars or rods are pivotally connected as at 72 to the respective crank arms 71, (as shown more clearly in Fig. 5). The crank arms are connected by means of a shaft 73 extending across the machine and is journaled in suitable bearings preferably inthe uprights 32. Thus it Will be manifest that when the shaft 73 is rotated, both of the crank arms 71 Will be rotated and they in turn will move the arms 67 about their points of pivotal supports to cause the dogs 68 to move out of one of the notches 67 a and into a position to enter another of the notches, during a portion of the revolution of `the cranks 71. During the remaining portion of the revolution of these cranks they will move the arms 67 in the opposite direction to impart one step of rotation to the ratchet disk 66 and also to the sprocket Wheels 59, 63, and this motion which is imparted to the conveyer sections 50 Will be imparted to the conveyer sections 49, 48, 47.

1n order to retard the movements of the arms 67, a dash pot 74 (see Figs. 2 and 5) is provided and is pivotally supported as at 75. The piston rod 76 is pivotally connected to one of the crank arms 71. Motion is imparted to the shaft V73 from the shaft 77 of the machine (see particularly Figs. 13

and 16) and this shaft is journaled in suitablebearings 78 supported by any fixed Aportion ofthe `frame Work, preferably one of the intermediate standards or uprights 31. This shaft 7 7 is provided with a series of pulleys 79 over which the 'drive belt 80 passes and is adapted to be shifted from one of the pulleys to another in order to vary the speed of rotation of the shaft 77. other shaft 81 (see Fig. 13) is provided With a series of pulleys 82 corresponding with the pulleys 79 on the shaft 77 and the drive belt 8O passes over and is adapted to be shifted from one of these pulleys 82 vto another, (see also Fig. 15). The shaft 8l receives its motion from any suitable source, preferably by means ofa belt which is adapted to pass I over the fast and loose pulleys 83, 84 on the shaft 81.

A iiy wheel 85 is provided on the shaft 77 and a Wormgear 86 is secured to this shaft for rotation `therewith and meshes with a Worm gear87 (see-particularly F gs. lOvand 1 6) on a stub shaft 88. Another Worm gear 89 is secured to the shaft S8 for rotation with the Worm gear 87 and this Worm gear 89 meshes with a Worm gear 90 secured to `the shaft 91 for rotation therewith and which shaft constitutes the main drive shaft for the machine (see also Figs. 13 and 16) inasmuch as the motion of all of the parts to be hereinafter described is derived from this shaft. The shaft 91 is journaled in suitable bearings preferably in the intermediate uprights or standards 3l and extends across the machine and secured to this shaft is a sprocket Wheel 92 (see Figs. 2 and l0) over Which a sprocket chain 93 passes. This sprocket chain also passes over a sprocket gear 9e (see also Figs. 5, G and 7) on a stub shaft 95 which latter is journaled in suitable bearings adjacent the shaft 73. A mutilated gear designated generally by the reference numeral 96 is also secured to the stub shaft 95 and for rotation with the sprocket gear 9e, and a mutilated gear 97 is secured to the shaft 73 for rotation therewith and the teeth of these gears 96, 97, are adapted to mesh so as to impart intermediate rotation to the shaft 73 and the smooth portions of the gears 96, 97 are constructed to constitute the ordinary and Well known form of Genera lock. rlhus it will be manifest that when motion is imparted to the main drivingshaft, which motion is continuous, it will be imparted by means-of the sprocket chain 93 to the stub shaft 95 and the motion of this shaft will be intermittently imparted to the shaft 73 through the medium of the gears 9G, 97, and this intermittent movement of the shaft 7 3 will, through the medium of the pawl and ratchet mechanism 68, 66, impart an intermittent advancing movement to the mantle conveyers.

Each of the sections of the conveyers are provided with pockets or seats 98 adapted to receive the ends of the mantle support 99 see Fig. 2l), and the sections of the conveyers are so arranged with respect to each other that the ends of adjacent sections overlap in order that the mantle supports may be automatically delivered from one section of the conveyer to the neXt adjacent section.

lThe present machine is adapted for the manufacture of two different types of mantles which are lrnovn as upright mantles and inverted mantles. In the manufacture of these different types of mantles, the shaping and hardening burners Which are adapted to operate upon one type are not adapted to operate upon the other type and therefore in order to adapt this machine for the manufacture of both types, burners must be provided which are necessary for the respective types and it is further necessary to provide an improved machine of this class whereby one set of burners or the burners necessary for a particular type may be rendered inactive while the burners necessary for the manufacture of the other type are rendered active. r)This is necessary because inverted mantles are provided With seams at their tips While the open ends are secured to a rim and the shaping burners are inserted into these mantles from the top While the tips, or the seamed portion of the mantles must be hardened from the outside. In the upright mantles, both ends are open and the shaping and hardening is effected from the inside of the mantle, the burners for performing this operation being inserted into the mantles from the bottom. It is also advisable in a machine adapted for the manufacture of upright mantles to provide a burner for initially or partially shaping the mantles before they reach the main shaping burners. rlhe machine will first be described as being adapted for the manufacture of the inverted type of mantle.

The mantle holder 99 may be of any desired shape and conguration and of a length to extend entirely across the machine so that the ends of the support will rest in the pockets 98 of the conveyer sections arranged at the opposite sides of the machine (see particularly Figs. 2l. and 24e). Depending from these supports 99 are hanger n'iembers 100, one of which is provided for each of the mantles lOl and these hanger members may be provided With projections or lingers 192 for receiving the ears or projections 109 on the ring lO-lmantle 191 is secured. Before the supports are placed in the machine the mantles lOl are connected with the respective hanger members 100 and these hanger members 100 are preferably tubular in construction as shown and register with an aperture or opening l05 in the supports 99 so as to permit the burners. to be hereinafter described, to be inserted into the mantles support 99 and to be `Withdrawn from the mantles after the resjieetive steps of operation. After the mantles have been thus connected to the supports 99 the latter are placed Within the pockets on the conveyer section 47, it being understood that during the operation of the machine the conveyer sections are all subjected to intermittent advancement. fter the mantles pass from the conveyer section 7 they pass to the sections d8 and arranged at a suitable point in the advancement of the mantles, preferably after they have been delivered to the conveyer sections 48, they are subjected to the burning` o'tli operation. The burners for this operation will now be described` reference being had more particularly to Figs. l, i9 and These burners are arranged adjacent the front of the machine and preferably consist of a pair of parallel pipes 106 spaced from each other and extending across to which the through the the machine. At the ends of these pipes 106 are arranged upright tubular portions 107 which are connected to a lT-coupling 108, to the inlet of which latter is connected a flexible supply pipe 109 for supplying gas to the pipes 106. These pipes are spaced from each other' and are each provided with a plurality of burners 110 projecting laterally therefrom with the burners of one pipe projecting toward and terminating short of the burners of the other pipe a suliicient distance to permit the mantles to stand between the burners. r1`he pipes 106 aresupported for vertical reciprocatory movement in any suitable manner, preferably by means of a. frame comprising uprights 111 which move through suitable guides 112 and a cross bar 113 which connects the upper ex tremi'ties of these uprights. The connection between the upright tubular ends of the pipes 106 with the T-coupling 108 passes over the cross bar 113 and forms a hanger or support for one end of the burner while a hanger 11-"1, which is supported by the cross bar 113, forms a support for the other end of the burner and the flexible pipe 109 which is connected to the supply pipe 115 will permit the burners to be thus reciprocated. These burners are adapted to be elevated so as to be moved out of the way or raised above the upper runs of the conveyer sections i13 to permit one of the supports 99 and the mantles held thereby to assume a position. that the mantles will stand between the burner tips 110 when the burner is lowered. (as shown more clearly in Fig. 3) and so as to be moved up and out of the way, after the burning off, to permit these mantles to be further advanced.

The gas for the burners is supplied through the pipes 109, 115, (see particularly Figs. 1 and 15) and the pipe 115 receives its supply through a mixing valve 116, the specific construction and operation of which latter forms no part of the present invention, sullice it to say that the valve is so constructed that when it is ojiened, the proper mixture of air and gas will be supplied to the pipe 115. 11n air pipe 117 and a gas pipe 113 are connected with the mixing valve 116 and these air and gas pipes (see Fig. 15) receive their supply from any suitable source. Valves 119, 120 are respectively provided in the pipes 117, 11S, for the purpose of regulating the pressure supply to the burner and additional valves 121, 122, may also be provided in the pipes 117, 11S, between the valves 119, 120 and the mixing valve 116 for a further or liner regulation of the supply of iiuid to the mixing valve. The mixing valve 116 is adapted to be automatically opened and closed at the proper times and so that when the burners are in the position shown in F ig. 3 with respect to the mantles 101, the valve will be opened to its full extent to of the machine.

permit the l'gasand the air pressure to be supplied to the burners and when the burners are elevated so as to permit the mantles which have been burned off, to advance, the mixing valve will be adjusted to shutoff the air pressure supply and a portion of the gas supply, so that only a small flame will be maintained at the burners. This automatic opening of the valve 116 is preferably accomplished from the main driving shaft 91 (see particularly Figs. 1, 2 and 3) and for this purpose there is provided on the shaft 91a cam 123 which coperates with a pivotally supported arm 121 having an extension 125 which latter is connected by means of a link 126 with the operating handle 127 of the valve 116. The cam 123 is so timed with respect to the arm 124 that at the proper interval it will operate upon the arm to open the valve against the tension of an elastic member 12S which latter tends nor-V mally to move the operating handle 127 of the valve 116 in a direction to close the valve.

rl'he burners are given their vertical reciprocating movement from the main drive shaft 91 in a manner which will now be described, reference being had more particularly to Figs; 1 to l and 15. The uprights 111 are connected by means of a cross bar 129 (see also Fig. 25) preferably in the form of an angle bar, a portion of which projects into the bifurcated extremities 130 of the uprights and a fastening device 131, such as a cotter pin, detachably secures the cross bar to the uprights. A shaft 132 extends across the frame adjacent the uprights 111 and is journaled in bearings mounted upon suitable fixed supports 133, which latter are arranged adjacent `the base of the machine. Sprocket wheels 134 are secured to the shaft 132: for rotationtherewith and yone of these sprocket Vwheels is located adjacent each side Flexible members 135 in the form of sprocket chains are provided which. pass each of thefsprocket wheels 134. vOne extremity of each of ythese sprocket chains is secured to the cross bar 1'29`and the other extremities `thereof support 1.a counter-balancing weight 136. Thus it will be manifest that when the shaft 132 is rotated the ,sprocket wheelst134rwhich rotate therewith will `operate upon the sprocket chains 135 tofraise or. lower the frame which supports the burners r-as well as raise and lower the counterbalancing weight 136. In order to frotate the shaft 132 another sprocket wheel is provided on the shaft 132 over which a sprocket chain'137 passes and this sprocket chain also passes overV `a sprocket wheel 133 on .another shaft 139 vwhich is Varranged parallel with the shaft 132 and extends acrossthe frame in a 'similar manner, the extremities thereof being -journaled fin suitable `.bearings on the supports 133. A HeXible member 140, preferably in the form of a sprocket chain, passes over a sprocket Wheel on the shaft 139 and also over another sprocket Wheel on a shaft 141 located preferably about midway of the machine, (see particularly Figs. 2, 4 and 15). This shaft 141 is rotated by means of a pinion Wheel 142 secured to the shaft and a toothed segment 143 is pivotally mounted as at 144, the teethV of which mesh With the pinion 142 and is adapted to impart a rotary motion to the pinion when the segment is oscillated about its point of pivotal support. This oscillatory motion is imparted to the segment by means of a cam 146 (see particularly Figs. 4 and 16) on a stub shaft 147 adjacent the shaft 91 and a gear 148 is secured for rotation With the cam 146 and this gear 148 meshes With a gear 149 on the shaft 91. |The cam 146 is adapted to engage a projection 150 on an extension 151 of the segment 143. Thus it Will be manifest that when the shaft 91 is rotated in the manner as has already been described, this rotary motion will be imparted to the cam 146 and as the latter rotates it will rock the segment 143 in one direction and thereby rotate the pinion 142 as Well as the shaft 141 and this rotary motion of the shaft 141 Will in turn be imparted to the shaft 132 through the medium of the connecting endless iierible members 140, 137 and the associated sprocket Wheels. The segment Will be moved in the opposite direction by the pinion 142 inasmuch as the Weight 136 and other similar Weights which Will be hereinafter more specifically described tend to rotate the shaft 141 in the opposite direction when the high portion of the cam passes out of engagement with the projection 150 on the extension 151 of the segment 143.

After the mantle has been burned 0E by the burners 110 it is intermittently advanced to the shaping and hardening burners and in order to permit a complete burning ofi before the mantles reach the shaping and hardening burners, these latter burners are spaced the required distance from the first mentioned burners.

TWO sets of burners 152, 153 are provided (see particularly Figs. 2, 4, 10 and 13) and are arranged to extend across the line of feeding movement of the mantles with one set arranged in advance of and spaced from the other set preferably a sufoient distance to permit the mantles by one step of advancing movement to move from the front series 152 to the rear series 153. These burners are adapted to be projected into the mantles 101 through the openings 105 in the supports 99 and through the tubular hanger members 100, as shown more clearly in Fig. 24.

1s the construction of each set of burners is the same, the specific description of one set will apply equally as Well to the others and as the individual burners of these sets are constructed the same, the description of one Will also apply equally as Well to the remaining burners.

rllhe burners are connected to a head, designated generally by the reference numeral 154 see particularly Fig. 20), having therein an air chamber and a gas chamber 156. The head 154 is provided with a plurality of recesses into which the upper eX- treniities of the burner tubes 152 project. rlie diameter of the ends of the burner tubes which are inserted into these recesses is somewhat less than the diameter of the recesses and the extremities of the burner tubes are provided With circumferential flanges 157. A collar 153 of a diameter to fit the recesses is sleeved over the burner tube so that the circumferential flange 157 Will engage and rest upon one edge of the collar and the collar is secured against dis placement With respect to the head 154 by suitable fastening devices 159. rEhe bore of the collar through which the extremity of the burner tube projects is tapering or of increasing diameter from the inner end or the end against which the flange 157 rests to the outer end so that the burner tube will be suspended for free lateral movement With respect to the head. This construction is provided in ordei to permit the burner tips 160 to always enter the mantle properly and to permit the burner tubes to yield or shift in the event that the tip of the burner should strike one of the rings 104 of the mantle. rThe air chamber 155 has communication with the burner tube 152 through the medium of a passage 161 controlled by a needle valve 162 and the gas chamber 156 has communication with the recess into Which the end of the burner tube is inserted by means of a passage 163 controlled by a needle valve 164 so that the mixture of air and gas which is supplied to the burner may be regulated. rl`he extremity of the burner tip 160 is provided With a central reduced opening 165 with which a series of radial slots 166 communicate and this burner tip is removably secured to the extremity of the burner tube 152 by suitable fastening device 167 so that the burner tips may be readily removed Wnen desired.

Both of the series of burners 152, 153 are supported for a vertical reciprocatory movement so as to move the burner tips into and out of the mantles at the proper time. ln order to accomplish this the heads 154 of the respective series of burners 152 are removably supported between plates or members 163 arranged adjacent the ends of the heads i and fastening devices 169 are provided which pass through open slots 170 in the plates or members 163 and into the ends of the heads. Trunnions 171 project beyond the members 168 and the trunnions 171 of the series of burners 152 `are journaled in uprights 172 arranged on opposite sides of the machines and passed through suitable guides supported by the members 433 (see particularly Figs. 10, y12 and 13). The lower extremities of these uprights 172 are connected by means of a cross bar 173 similar'to `the manner in which the uprights 111 are-connected by the cross bar 129 and these uprights 172 are adaptedto be reciprocated vertically in order to raise and lower the burners 152 in a manner somewhat similar to the manner in which the uprights 111 are raised and lowered, that is, by means of iexible members 174 `(see also Figs. 2, 4 and 13) which pass over sprocket wheels 175on a shaft 176 extending across the machine with its ends journaled in suitable bearings. `One extremity of these flexible members 174 are connected to the cross bar 173 and to the other extremities a counterbalancing weight ,177 is connected. The shaft 176 is rotated by means of a pinion 178 with which the teeth'of a segment 179 mesh.- This segment ispivotally supported as at180 and isprovided with an'arm or extension 181 having a projection 182 thereon which is adapted to be engaged by a cam 183 on a shaft 184. When `the shaft is rotated the segment 179 willbe moved about its pivot in one direction to rotate the shaft 176 and thereby elevate the burner head 154 and the burners 152. When the high portion of the cam passes out of engagement with the projection V182 on the segment, the weight of the parts will cause the burners 152 to be low eredrso as to pass into the mantles. The shaft 184 receives its motion from the main driving shaft 91 through the medium of an idle gear 185 (see Fig. 4) which meshes with the gear 148 and also with the gear 186 on the shaft 184. Thehead 154 of the series of burners153 is given its vertical movement in a similar manner and for this purpose the trunnions 171 of this head are journaled in the ends of uprights 187 which pass through suitable guides and the lower extremities thereof are connected by means of a crossbar 188 (see Fig. 10) similar to the manner in which the cross bar 129 connects the'uprights 111. These uprights 187 are located in proximityto the shaft 141 as shown clearly in Fig. 2 and flexible members 189m the form of sprocket chains pass over sprocket wheels 190 on the shaft 141 with one extremity connected with the cross bar 188 and supported by the other extremities of the iiexible members is a counterbalancing weight 189. Inasmuch as these sprocket wheels 190 aresecured for rotation with the shaft 141 and as'the shaft 141 is rotated by the oscillation of the segment 143 already described, it will be manifest that when the shaft 141 is rotated in one direction,l the uprights 187 as wellas the series-of=burners 153V will be'moved in one-direction to raise the burners out of the mantles and when the shaft'j141 is rotated in the opposite direction the burners will be lowered into the mantles. Suitable stop collars 190 may be provided on the uprights 172 and 187 for limiting the downward movements of the respective series of burners 152, 153.

In order to properly `position the heads 154 of the respective series of burners 152, 153, so as to properly present them to the mantles in the event of wear of the parts, adjusting devices may be provided for each of the heads 152 (see particularly Figs. 11 and 12) in the form of an arm 191 which is connected with one of the trunnions '171 so as to depend below the heads. This arm 191 isprovided with an enlarged extremity 192 havingllaterally projecting ears 193,7one arranged-on each side of the adjacentupright 172 and adjusting screws `194 are threaded through the respective ears .-193 intoengagement with opposite sides of the upright 172 and are adapted to rock the head 154 about its point of pivotal support., Lock nuts 195 are provided forthe adjusting screws forholding them in their adjusted positions.

Gas issupplied to the burner head 154 of the series of burners 152 from the gas supplypipe 118 through the medium of a tube or pipe 196 (s ee particularly Figs. 1 `to 4, and 13 and 15), which pipe 196 is provided with a. hand valve 197, by means of which the supply of gas to the pipe may be shut off, and an upright portion 198. A flexible tubularmember 199 is connected with the extremity of the upright portion 198 and also to a tube or pipe 200which latter leads into thefgas chamber of the head v154. A spring controlled valve 201 is provided preferably in the upright portion 198 of the pipe 196 and an operating' handle 202 is adapted to open the valve. rIhis valve 201 andthe remaining gas and air controlling valves which are operated automatically, may be of any desired and well known construction and form no part of the present invention, suffice it to say that at certain intervals, the operating handles of the respective valves are actuated to open the valves, and the valves being of a spring action, vare automatically closed at the proper time.

Air is supplied to the head 154 of the series-ofburners 152 through a pipe 203 (see particularly Figs. 4 and 13)y which has.com munication with the air chamber -of the head 154 and a tubular fiexible member 204 isfconnected to the inlet of the tube 203 and alsowith a pipe 205 leading fromrthe air supply pipei117, (see Fig. 15), andaspring controlled valve 206, Vsimilar to the valve 201, is providedin the-pipe205 for automatically controlling .the passa-ge of air iis its

memes through this pipe. A hand valve 205a is provided in this pipe for permanently cutting off the supply of air to the pipe and for regulating the amount of flow through the pipe.

The pipes 200, 203, are preferably rigidly connected with the head 154 and move upwardly and downwardly with the head, the flexible tubular members 199, 204, permitting this action.

Gas and air are supplied to the head 154 of the series of burners 153 in a similar manner and for this purpose a pipe 207 (see particularly Figs. 2, 4, 8 and 15) leads from the gas supply pipe 118 to a point adjacent the series of burners 153 and is provided at its ends with branch pipes 208, 209. rThe pipe 208 is provided with an upright extremity 210 to which one extremity of a tubular iiexible member' 211 is connected and the other extremity of this tubular member 211 is connected to a pipe 212, which latter discharges into the gas chamber of the head 154 of the series of burners 153. A spring controlled valve 213 similar to the valve 201 is provided in the upright pipe 210 and an operating handle 214 is also provided for opening the valve. A cut off valve 215 may also be provided in the pipe 208 for cutting olf the supply of gas to the pipe 210. Air is supplied to this head 154 of the series of burners 153 from a pipe 216 leading from the air supply pipe 117 (see Figs. 3, 4 and 15) which extends parallel with the pipe 207 and terminates in two branch pipes 217, 218. The pipe 217 is provided with an upright portion 219 to which one extremity of a tubular exible member 220 is connected. The other extremity of this tubular member 220 is connected at one extremity of a pipe 221 which latter discharges into the air chamber of the head 154 of the series of burners 153. A hand valve 222 (see Fig. 15) is provided in the pipe 217 for shutting 0E the supply of air to the pipe.

A spring controlled valve 223 similar to the valve 213 is provided in the upright portion 219 in the supply pipe and this valve is also provided with an operating handle similar to the handle 214.

The valves 201, 206,213 and 223 are adapted to be automatically opened at the proper intervals in any suitable manner such as by means of cams operated from the main driving shaft 91 (see particularly Figs. 1 to 4, 10 and 13). The cams 224, 225, for respectively operating the gas and air valves 201, 206, are secured to the shaft 184 for rotation therewith and these cams are adapted to respectively operate upon the arms 226, 227 which latter are pivoted loosely upon a support 228, to rock the arms about the support in one direction and the arms are respectively connected by links 229 with open the valves 201, 206. inasmuch as one f of these valves controls the supply of gas and the other controls the supply of air, and it is advisable to admit the supply of gas to the burners 152 in advance of the admission of the supply of air to the burners, the

cam actuating the gas controlling valve may be so constructed with relation to the cam which controls the air supply valve so as to open the gas valve in advance of the air p lvalve and the cam controlling the air valve may be arranged so that the air may be gradually supplied to the burners and thereby gradually increase the pressure or force of the flame at the burners to gradually shape the mantles.

The cams 230, 231, (see particularly Figs. 4 and 8) which control the valves 213, 223 are secured to the shaft 91 for rotation therewith and arms 232, 233, similar to the arms 226, 227, are mounted for rocking movement upon a support 234 and are respectively connected by means of links 235 similar to the links 229 with the operating handles 214 of the valves 223 and these cams 230, 231 are so constructed and arranged with respect to each other that one will operate to open its respective valve in advance of the other similar to the operation of the cams 224, 225.

The burners 152 preferably project below the tips of the series 153 so that when the burners 152 are inserted into the mantles, the tips will extend for some distance into the mantles to serve as a means for shaping and hardening the lower portion of the body of the mantles, while the tips of the series of burners 153 will not project to such an extent into the mantles, the object of this arrangement being that the last mentioned set of burners will operate upon the mantle to assist in shaping the same and also for the purpose of hardening the portion of the mantle and the stitching around the supporting ring 104.

After the mantles have passed from the burner 153, the next step of their advancing movement will cause them to assume positions over another set of burners 235 (see particularly Figs. 2, 4 and 8). These burners 235 are arranged some distance below the tips of the burners 152, 153, and project up- 1 c wardly toward the tips and are connected to a head 237 similar to the heads 154. This head is adapted to be moved in a vertical plane so as to move the tips of the burners toward or away from the tips of the depending mantles, in a manner similar to the manner in which the heads 154 are moved, that is, by means of uprights 238, which move through suitable guides and to which the head 237 is pivotally connected as at 239.

The lower extremities of these uprightsare detachably connected to a cross bar 240. Flexible members 241 pass over sprockets 242 (sce also Fig. 2) with one extremity connected to the cross bar 240 and with a counterbalancing weight 243 connected to their other extremities. The sprockets 242 are secured to a shaft 244 which is adapted to be rotated by means of a pinion 245 secured thereto and with which pinion the teeth of a toothed segment 246 mesh. This segment is pivotally supported as at 247 preferably upon the support 234 and is provided with an extension 248 having a lateral projection 249 adapted to be engaged by a cam 250 secured to the shaft 91 so that when the shaft` is rotated, the segment 246 will be oscillated and the head 237 with the burners 236 thereon will be correspondinglyraised or lowered. The head 237 is adapted to be rocked so as to properly position the tips of the burners 236 in a manner somewhat similar to the heads 154, that is, by means of a depending arm constructed of sections 251, 252. The section 251 is connected with one of the end plates 253 and its free end is pivotally connected as at 254 (see particularly Fig. 9) to the adjacent end of the section 252. A pin and slot connection 255, 256 is also provided between the adjacent ends of the sections 251, 252, which pin is adapted to be loosened to permit the sections 251, 252 to be adjusted about the pivot 254, and when thus adjusted to be tightened to hold them in their adjusted positions. The section 252 is provided with a lateral projection 257 having a bifurcated portion to receive one of the uprights 238.

Gas and air are supplied to the head 237 of the burners 236 from the pipes 207, 216, and for this purpose the branch pipe 209 of the gas pipe 207 (see also Figs. 8 and 15) is connected by means of a tubular flexible member 258 with the inlet 260 similar to the valve 213 is provided in pipe 209 for automatically controlling the supply of gas through this tubular pipe 258. A cam 261 is provided on the shaft 91 for opening the valve 260 through the medium of an arm 262 pivoted to the support 234 and which arm is connected by means of a link 263 similar' to the links 235 to the operating handle of the valve. The air is supplied to the head 237vfrom the air supply pipe 216 through the branch pipe 218 and also through a flexible tubular member 264 which latter has communication with the inlet opening 265 of the air chamber in the head 237. A spring controlled valve 266 similar to the valves 213, and 260 is provided in the pipe 218 and this valve is adapted to be opened by means of a cam 267 on the shaft 91 which operates on an arm 268 pivoted to the support 234 and which arm 268 isconnected by'means of a link 269 with the operating handle of the valve 266. The flexible pipes 258,264, will permit the head 237 to be raised'and lowered. After the mantle tips have been hardened, the next step of advancing movement will cause the mantles to move away from the hardening burners 236. Obviously, the pressures in the series of burners 152, 153 and236 may be varied with respect to each other by adjusting the various hand valves so that the desired and necessary pressures of the flame may be obtained for the shaping and hardening operations on the mantles.

After the mantles have passed from the burners 236 they will havebeen completely shaped and hardened and the next step of operation is their immersion into a preserving solution. It is necessary, however, that the mantles be allowed to become cool and.

in order to accomplish this the tank 270 (see particularly Figs. 2, 4 and 5) containing the solution into which the mantles are to be immersed may be arranged at aV suitable distance from the burners 236. This tank 270 is adapted to be raised and lowered so as to be brought into a position to receive the mantles and after the mantles have been immersed to be lowered so as to move out of the way to permit the mantles to beV further advanced and carried away from the machine. In order to accomplish this the tank 27 0 is mounted upon a suitable support 271 connected to uprights 272 which move in suitable guideways with their lower extremities connected by a connecting bar 273. Flexible members 274 pass over sprocket wheels 275 mounted upon a shaft 276 extending across the machine and j ournaled in suitable bearings. The flexible members 27 4 are connected by one extremity to the cross bar 273 and a counterbalancing weight 278 is connected to their other extremities. rlhe shaft 276 is given a rotary motion by means of a crank arm 279 connected by a link 280, preferably to the gear96 V(see particularly Fig. 7) so that when the gear 96 is rotated in the manner` as already describedbyy the endless chain 93, the shaft 276 will be rotated and the tank 270 will be raised or lowered. The tank may be limited in its lowering movement by means of a stop collar 281` onone of the uprights 272. which engages a fixed body.

The liquid may be suppliedto the tank.
